I didn’t understand the significance of the title clock in this story, told from the point of view of Marta who could have been a brilliant mathematician, but such was not allowed in 1950s America, so instead we hear of Marta’s grandmother’s clock and a search for the missing grandmother, meeting (along the way) at least one old woman who seems out of time.
Grandma and I have a theory about how John Carter found his way to Mars. We think we can explain it with Schrödinger’s equation.
